Abstract

The invention discloses a directional adjustable expanding umbrella conveniently mounted on a sunshade umbrella under the condition of keeping the present sunshade umbrella unchanged. The directional adjustable expanding umbrella comprises a plurality of umbrella skeleton structures and a plurality of pieces of sunshade cloth; each of the umbrella skeleton structures comprises a fixed rod and a rotating rod; a fixing device connected with the sunshade umbrella skeleton is fixed on the fixed rod; the rotating rod is rotatably connected with the fixed rod through a connecting device; and the sunshade cloth is connected with the adjacent rotating rods. The directional adjustable expanding umbrella has a simple structure; a sunshade area can be directionally expanded; and a sunshade angle can be adjusted.

Description

Be installed at the directed scalable expansion umbrella on the parasols

Technical field

The present invention relates to a kind of directed scalable expansion umbrella that is installed on the parasols.

Background technology

At present, the scope of application of parasols is more and more wider, and is also increasingly high to the requirement of parasols.Parasols of the prior art generally is connected to form a vertex of a cone by some bracing frames and some skeletons and forms; Have Stability Analysis of Structures like this, be difficult for advantage such as being fallen by wind; But its sunshade area is generally fixed; Often all require directed sunshade area and the adjustable-angle that enlarges parasols in a lot of uses, the orientation that lacks parasols now on the market is extended this product sale of umbrella.

Summary of the invention

The objective of the invention is to overcome the defective of prior art; Provide a kind of under the situation of not changing existing parasols; Conveniently install the directed directed scalable expansion umbrella on the parasols that is installed at that enlarges the sunshade area and can regulate the sunshade angle of simple in structure, ability additional.

The technical scheme that realizes the object of the invention is: a kind of directed scalable expansion umbrella that is installed on the parasols; It comprises some rim structure of umbrella and some puggarees; Rim structure of umbrella comprises fixed bar and dwang; Be fixed with on the fixed bar and be used for the fixture that is connected with the parasols skeleton, dwang is connected with fixed bar through jockey rotationally, and puggaree is installed on the adjacent dwang.

Further, described fixed bar is provided with some spacing catch, and spacing catch is positioned at the both sides of fixed bar.

Further, described jockey is connected with fixed bar through bolt, is set with spring on the bolt, and an end of spring and the bolt head of bolt offset, and the other end and jockey offset.

Further, the position that contacts with fixed bar on the described jockey is provided with first plane teeth, and fixed bar is provided with second plane teeth that matches with first plane teeth.

Further, described fixture is flexible fixed band.

After having adopted technique scheme, fix through the umbrella frame of fixture on the fixed bar and parasols, the position-limited block of fixed bar can be used for controlling fixing scope and angle; After dwang was fit into jockey, jockey can be connected through bolt with fixed bar, played shaded effects after puggaree is installed to dwang; When needs are regulated the puggaree angle; The rotated bar gets final product, and has so just realized directed expansion sunshade area, and can regulate the sunshade angle; When the rotated bar; Under the effect of second plane teeth of first plane teeth of jockey and fixed bar; Axial distance becomes big between jockey and the fixed bar, the withdrawal then because spring stress in the jockey stretches, and jockey and fixed bar axial distance diminish; Recover lock-out state, thereby make that the rotational angle of dwang is fixed.

The specific embodiment

For content of the present invention is expressly understood more easily, below according to specific embodiment and combine accompanying drawing, the present invention is done further detailed explanation,

Embodiment one

Like Fig. 1, shown in 3; A kind of directed scalable expansion umbrella that is installed on the parasols; It comprises two rim structure of umbrella 8 and a puggaree 7, and rim structure of umbrella 8 comprises fixed bar 3 and dwang 1, is fixed with on the fixed bar 3 to be used for the fixture 4 that is connected with the parasols skeleton; Dwang 1 is connected with fixed bar 3 through jockey 2 rotationally, and puggaree 7 is installed on the adjacent dwang 1.

As shown in Figure 1, fixed bar 3 is provided with two spacing catch 3-1, and spacing catch 3-1 is positioned at the both sides of fixed bar 3.

As shown in Figure 2, jockey 2 is connected with fixed bar 3 through bolt 6, is set with spring 5 on the bolt 6, and an end of spring 5 and the bolt head of bolt 6 offset, and the other end and jockey 2 offset.

As shown in Figure 1, the position that contacts with fixed bar 3 on the jockey 2 is provided with the first plane teeth 2-1, and fixed bar 3 is provided with the second plane teeth 3-2 that matches with the first plane teeth 2-1.Fixture 4 is flexible fixed band.

Embodiment two

Like Fig. 1, shown in 4; A kind of directed scalable expansion umbrella that is installed on the parasols; It comprises three rim structure of umbrella 8 and two puggarees 7, and rim structure of umbrella 8 comprises fixed bar 3 and dwang 1, is fixed with on the fixed bar 3 to be used for the fixture 4 that is connected with the parasols skeleton; Dwang 1 is connected with fixed bar 3 through jockey 2 rotationally, and puggaree 7 is installed on the adjacent dwang 1.

The quantity of the puggaree 7 between the quantity of rim structure of umbrella 8 and the adjacent dwang 1 is looked concrete operating position and is decided, and is not limited to the quantity among embodiment one and the embodiment two.

Operation principle of the present invention is following:

Fix through the fixture on the fixed bar 34 and the umbrella frame of parasols, the position-limited block 3-1 of fixed bar 3 can be used for controlling fixing scope and angle, after dwang 1 is fit into jockey 2; Jockey 2 can be connected through bolt 6 with fixed bar 3; Play shaded effects after puggaree 7 is installed to dwang 1, when needs were regulated the puggaree angle, rotated bar 1 got final product; So just realize directed expansion sunshade area, and can regulate the sunshade angle; When rotated bar 1; Under the effect of the second plane teeth 3-2 of the first plane teeth 2-1 of jockey 2 and fixed bar 3; Axial distance becomes big between jockey 2 and the fixed bar 3, because the spring 5 in the jockey 2 is withdrawn by tensile then, jockey 2 diminishes with fixed bar 3 axial distances; Recover lock-out state, thereby make that the rotational angle of dwang 1 is fixed.

Above-described specific embodiment; The object of the invention, technical scheme and beneficial effect have been carried out further explain, and institute it should be understood that the above is merely specific embodiment of the present invention; Be not limited to the present invention; All within spirit of the present invention and principle, any modification of being made, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
